The* inventioh relates `to'ftrucks and hasfor 'its object toprovideaptruck preferably-A of the three "wheel type whereinthe load body l' is supported within-the frame in such*'amanA nerthat the operator `may at zany time as he@ moves the truck from yplace to place-by theyy handle; lutilize said handle jfor lowering the"y truck frame thereby causingfthe-load body to `come inf contact with; the ground so that the truck` frame asf it 1 further advances will leavethebody of thetruck onitheground.

Al further Objectis to* provide ar4 pair `of longitiidinally; disposed slotted" strips @dis- ""pose'idunder the body supporting angles at i each side of the frame7 saidV strips being pivoted and` supported fin such la `manner `that f as they "are movedy downwardly they Vwill re*- main in parallel relation'to'each*other and" to Athe vtruckV frame, thereby lowering the truclrbody which Ytheyvsupportrin a hori-f zontal plane; alsoto''provide'in'fconnectiony with the lowering strips leverageimeans controlled by the truck handle whereby the lowering strips may be movedy downwardly and the truck body deposited1 on the ground.

With the above andother objects in view the invention resides in the combination and arrangement ofiparts as hereinafter set yforth shown in the drawings, described and claimed, it being understood that changes in ythe precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention. t

In the drawings Fi 1re 1 is a side elevation of the truck showing the body ythereof in raised position.

therearend ofwhich-is open. `Each sidelz` comprisesspaced walls 3 and 4L yand disposed y between said walls 3 and 4c are the arms of angled members 6,' the' right angle arms Tof which extend'inwardly and-are adapted to support the! load-` carrying fb'ody 8"of ithe truck. The` body 8 'hassecured to its-under2 face' downwardly extending iianges 9 which` extendbelowfthe lowe'rlfaoes of' the rflanges 7' so ythat as the angle members' 6V are lowered the lianges-IQ will rest upon f the groundk and f maintainfthe 4body 8l spaced therefrom jsiiiii-y cientlyl toi allow inwardly extending flanges 7 'toppass from-underthey edges'ofgthe "body each other and by; `longitudinally Vj disposed bars 10` locatedat eachgsideofgthejtruclg frame `and supported-by linksl 11'` which have theirlower ends pivoted to' thev `bars 10 as l at' 12-land their upper endspivoted as at 13 in i'ch'ainberslfiofthe outer member 3 ofthe side 2 ofthe frame. It will'b'e seenfthat as the bars 10: arev moved forwardly *said bars will move upwardly thereby coming -into eri-g gagementiwith ,the angleimembers s'oasto y maintainy said angle `members?'between theil walls) 3-^ and v4l offthe' rsidesQ.` However,` duringtliisforward4 movement of the'supporting bars '10 the flugs which form-the pivotal 'i points# 12l will enter'the segmental slots 15 off brackets 16v which are securedA tothe walls 3 l yof the framez' 1 Segmental slotslform means for=-guiding the bars:Y 10fin their-'f upwardffy nievementdiiringfa raising (')peration-` andginr; a l downward movement; during l1a' lowering Pivoted to the forward ends of operation. the bars 10 are links 17, the forward ends of which are pivoted as at 18 to downwardlyk ing the lowering operation the arms 19 move rearwardly between the spaced walls 3 and 4. Lever 20 is adapted to be rocked so as to impart a forward and rearward movement to the bars 10 when it is desired to pick up a truck body or deposit the same. The picking up of the truck body is accomplished by the operator by moving the handle 23 and the angularly shaped bracket 23a rigidly carried thereby downwardly in the direction of the arrow a. This action will rook said handle on its pivotal point 24 thereby caus- "70 8,..therebyfdepositing the truck body and its)y load on the ground The langle'members 6l arey raised and loweredfin` parallel relation to `rate-need., Mar. 28,1922. y Application ineaysneptemima#` 19; i919; serial Nef 324,776(l l 1 ing the arm 25 of the bracket 23a which is by wheels 3l which are pivoted between the upper end of'a post 28 which is lrotatably mounted in a bearing 29 atthe forward `end`V of the frame and has at itslower end a sup-7 porting wheel 30. The rear end of the truck frame is supported spaced from the ground walls 3 and 4 ofthesides ofthe frame. f

F rom therabove it will be seenthat a truck is vprovided' whereinl the picking up or der positing of the truck body with its load may be quickly and easily accomplished and also eliminating the necessity of the operatorLv handling the truck body at any time.

`The invention having been set'forth what is elamedasnew andfuseful is :f i 1. Atruck comprising a frame, a

i saidframe having its rearfendopen, right angled. body supporti/ng members carriedvby the siderailsof the iframe, longitudinally disposedk barsengaging the under surfaces of the' right anglebo'dy supporting members, 4'said bars having link connections with the side rails 'of the truck frame, and lever means connected .to the bars whereby saidbars'mayf be simultaneously moved upwardly ork downf wardly in parallel relation with each other by-themovementof the truckhandle'.

2, A truck comprising a frame,` a handle, said frame having its rear end open,the sidesfiof said lframe being. provided with l` spaced. `walls', anglemembers having one-of their flanges Idisposed between Vsaid, spaced walls, the other flange of said angle members.

extending inwardly at lright angles and forming vmeans .for supporting the truck', body, bars disposedbelow the angle. .memf `f bersand-engagingthe'same, said bars hav-` ing link connections with the side railsof the frame, theforward ends of the bars having a link-connection .withfa right1ang1e bell handle,

crank lever, said bell crank lever being pivotally mounted in the frame, a link connecvtion"between the y"bell crank l'lever' and the z handle ofthe truck and'forming means'for rocking'the bell crank lever for moving the `bars forwardly or rearwardly thereby pick ing up or depositing the truck body as de'- slred and .wheels `or .supporting the truck `frame normally spaced from the ground( l 3. A truck comprising a U-shaped frameA having its transverse portion forwardly disposed, a second U-.shaped iframe disposed within the irstU-shaped frame and having itsarms secured to and spaced from-the arms oftheirst mentioned U-shaped frame andits transverse vportion-forwardlyl disposed,.elongated. right angle members having their verticalilanges vertically movable.vv between thearms ofthe U-shaped frames?, and their horizontal ilanges extending inf.
